Dawn VME Products announces PSC-6236 Universal AC input VITA 62 3U power supply

The PSC-6236 features a mission critical wide temperature range at high power on a 1 inch pitch.

Input range is 85-264 VAC, 47-400 Hz. The Dawn PSC-6236 can be special ordered to support high current single channel applications. The PSC-6236 offers current sharing with up to four power supplies in a system for outputs of 12V, 5V and 3.3V.

Models are available for air cooled, conduction to bulkhead cooled, and conduction to wedge lock cooled applications and configurations. The PSC-6236 is designed to be compliant with MIL-STD-461, MIL-STD-704F and MIL-STD-810F.

Dawn's proprietary embedded RuSHTM Rugged System Health Monitor technology actively measures voltage, current and temperature on each rail for intelligent monitoring and protective control of critical power supply performance parameters.

The PSC-6236 is interfaced to the Intelligent Platform Management Bus (IPMB) providing an I2C communication link with system cards. Onboard microprocessor and firmware provide real-time over voltage, over current and over temperature protective control, with factory programmable power sequencing and shutdown for all voltage rails.

Standard firmware provides Power on Hours and max/min temperature with time stamps via an on-board RTC. Firmware enables additional PSC-6236 additional features including customer specified monitoring windows for power sequencing, special alerts, alarms, status reports and other monitoring and control factors. An optional 3-axis accelerometer records and time stamps shock and vibration and other critical events.

The PSC-6236 front I/O panel includes an LED status indicator, a USB port for field firmware upgrades and VBAT battery access for support of the VPX memory backup power bus.

Being first to market with a universal AC input VITA 62 power supply demonstrates Dawn's commitment to VITA 62 power supply leadership, says Barry Burnsides, Dawn VME Products Founder and CEO. In addition to a wide range of standard features, the highly configurable Dawn PSC-6236 offers the mission critical market many non-standard features through custom firmware.
